血压是影响心血管疾病(cardiovascular disease,CVD)的主要原因,当室外温度降低时两者均增加。然而,关于季节性血压变异和CVD患者死亡率的关系尚不清楚。方法:研究人员对中国Kadoorie生物银行(Biobank)在2004-2008年从10个不同区域收集到的曾患CVD的患者23 000例,进行7年随访研究,记录到了1484例CVD死亡。应用基线调查资料评估季节性收缩压变异及其与室外温度的关系。采用Cox Blood pressure is the main cause of cardiovascular disease (CVD), and both increase when the outdoor temperature decreases. However, the relationship between seasonal variations in blood pressure and CVD mortality is not clear. METHODS: The researchers conducted a 7-year follow-up study of 23,000 patients with CVD who were collected by Koboorie Biobank from 10 different regions in 2004-2008 and recorded 1484 CVD deaths. Baseline survey data to assess seasonal systolic blood pressure variability and its relationship with outdoor temperature. Using Cox
